Pruvit Keto OS has become extremely popular as a way to stay in keto even if you have the odd carb slip up. Endorsements by such influencers as Joe Rogan have earned Pruvit a loyal following. So, we thought it was about time we put this exogenous ketone supplement to the test in order to separate fact from fiction.
Does Pruvit Keto OS really work?
Read on to find out.
What is Pruvit Keto OS?
Pruvit Keto OS is an exogenous ketone supplement. As such it is made up of a combination of BHB salts that are designed to deliver synthetic ketones into the bloodstream. This supplements the body’s natural efforts to get into ketosis through carbohydrate restriction. It has been scientifically established that getting into and staying in a ketogenic state helps people lose body fat.
By delivering external ketones into the bloodstream, BHB salts fool the body into thinking that it is already in ketosis. This can help to push a person over the edge and into ketosis. When that happens, they will start converting stored body fat into energy.
The people behind Pruvit Keto OS state that taking this supplement can help you to get into ketosis in as little as half an hour (more on that claim later!) Pruvit is a Hong Kong based company who has been in the supplement industry for a number of years.
Pruvit Keto OS comes in powder form, with each serving being between 12-16 oz. It can be mixed either with water or any zero carb liquid (taking it with a carb infused beverage would defeat the purpose of taking this product!).
Each serving of Pruvit Keto OS delivers 50cc of BHB based exogenous ketones to your system.
Keto OS comes in a caffeine added and a non-caffeine version (known as charged and uncharged). In addition to BHB, the other ingredient is MCT Oil.
Keto OS is available in two flavors:
- Orange Dream
- Chocolate Swirl

What Pruvit Claims Keto OS Will Do

Keto OS Benefits
Let’s now take a look at the things that Keto OS may potentially do. We’ll then see how good it actually is at delivering. So, here is what Keto OS may do:
- Help you get into keto faster – consistently cutting out the carbs in order to kick the body into the fat-burning state of ketosis is hard work. We could all do with a little help. And that is precisely what Keto OS promises to offer. The addition of exogenous ketones delivers reinforcements that have the ability to push you right into the fat-burning zone.
- Help you get rid of body fat – getting into keto will force your body to switch from a glucose burning to a fat-burning energy system. As a result, you will be burning off stored body fat to supply the energy that your body needs to function. Exogenous ketones will also help to suppress your appetite. In a 2014 study, a keto inducing diet led to a 50 percent reduction in appetite.
- Ward off keto flu symptoms – when you transition to keto, you will, unless you are very lucky, experience what is known as the keto flu. Symptoms are similar to the real flu. Exogenous ketones have the ability to help fight these effects. They provide energy to overcome lethargy, boost brainpower to overcome fogginess and help overcome nausea.
- Increase Endurance – Extra ketone means extra energy. They have also been shown to reduce lactic acid buildup and prevent the catabolism of muscle tissue. All of this means that you will be able to exercise harder for longer.
- Boost Brain Power – the keto diet was first developed in the 1920s to treat children’s epilepsy. Since then there have been many brain benefits associated with the ketogenic diet. Keto is also able to improve the memory of rats in a number of studies.
My Pruvit Keto OS Results
Ok, so we have seen all of the claims and potential benefits of Pruvit Keto OS. But do they really stack up? Here is my experience with Keto OS.
Because I am not a keto newbie, I wasn’t suffering from the keto flu while I was taking Pruvit Keto OS. As a result, I am not in a position to state whether it works to dampen the effects of the keto flu. But I can comment on its ability to provide extra energy for working out.
Pruvit Keto OS gave me a noticeable increase in energy for my workouts. I had more endurance, too. When taking the Charged option, the results in terms of energy production were even more pronounced. I also had a significant increase in training focus.
My fat loss was steady both while on and off Pruvit Keto OS, so it is hard to tell how much of an effect the supplement had.
My overall impression was that Pruvit Keto OS did a good job of boosting my training energy to allow me to train harder in the gym. Keep in mind, though that this product is not sold as a pre-workout supplement. The results I received in terms of fat loss were not what I was hoping for.

The Experience of Others
So, now that you know my experience with Keto OS, let’s take a look at what others have said about it. There are a lot of reviews online from real Keto OS users. Here’s a random sampling:
Toni was pretty good about sticking to a keto diet during the week. But it was a different story when the weekend rolled around. That was when she needed a boost to keep her on track. That is exactly what Keto OS did for her. In fact, it allowed her to lose an extra 8 kg!
Jeanette gave Keto OS a 3 month trial. She found that it did a good job of boosting her energy levels and controlling her hunger pangs. Both of those actors contributed to her weight loss. However, she wasn’t sure whether the exogenous ketones actually helped her lose more weight in themselves.
Popular Podcster Joe Rogan from the Joe Rogan experience promoted Pruvit Keto OS on his show. Joe lamented that fruit woud take him out of keto. He found that supplementing with Keto OS allowed him to enjoy his fruit – and stay in keto!
Here’s what Joe has to say about Pruvit Keto OS . . .
‘The big difference, with carbs, I experience inflammation. More soreness, fatigue, insulin crash… all the factors that don’t happen when I eat high fat, low carb.’
It is important to keep in mind that results from Pruvit Keto OS only cone when you are exercising and eating low carb at the same time.
Keto OS Versions
There are three different versions of Keto OS as follows:
- Keto OS
Flavors – Orange Dream / Chocolate Swirl
- Keto OS Max – beefed up ingredients
Flavors – Maui Punch / Swiss Cacao

Where to Buy Famous Keto?
We strongly recommend purchasing Famous Keto directly from the manufacturer’s website or from Amazon. As we have already inferred, the keto diet supplement industry contains some unscrupulous operators. Going direct to the source is always the best option.
Famous Keto is the real deal. It delivers a on-two punch of extra ketones and antioxidants to deliver faster fat burning, improved energy and free radical protection. The price is reasonable and the taste pleasing. We recommend Famous Keto to anyone who is serious about getting into keto and staying there. Just keep in kind that you will need to be following a low carb/high-fat diet for this product to benefit you.
